VEHICLE-WHEEL.

SPECIFICATION forming part of Letters Patent No. 352,141, dated November 9, 1886.

' Application filed February 20, 1886. Serial No. 192,698. (No model.) i

To all whom it may concern.'-

vBe it known that l,` JAMES MACPHAIL, a citizen of the United States, residing in the city of Rockford, in the county o f Winnebago and State of Illinois, have invented a new and useful Improvement in Vehicle JWheels, of which the following is a speciiication.

This invention relates to a class of wheels known as the tension-wheel,7 largely em ployed in the manufacture of wheeled agricultural implements. Its object is to imy prove this class of wheels by the employment of a light-weight three-part hub of easy construction, capable of renewal in its several parts, but more especially in the parts most subject yto wear. To this end I have designed Y and constructed the hub represented in the accompanying drawings, in which- Figure l is an isometrical' representation of a hub embodying my invention. Fig. 2 is a lengthwise central section, and Fig. 3 is also .a lengthwise central section of my improved hub, showing a slight structural modification.

My improved hub consists, essentially, of a thimble, A, and removable heads B and C. The thimble A of my improved hub is of a construction to receive the axlearm to re'- volve thereon in the usual manner, and, if required, it may be chambered in any'of the known or usual forms. vIhe end portions of the thimble are tapered or produced on its outer surface in truncated conic form of least diameter at their extreme ends. IIhe end portions, B and C, of the hub are produced in annular ring form, and in section are of the horseshoe or Uv form, and their axial openings are of a conformation to receive the conic ends ofthe thimble snugly. Perforations D, to receive the inner ends of the spokes, are formed at proper intervals in the outer rim of the an- V nular ring-hub ends;

l The several parts consisting of the thimble A and theannular ring-hub ends are of a conthe annular ring-head ends, o r either of them,

become unfit for use,'either or both of them may be removed and a new one put in its place. Y Y

The several parts of my improved hub are .of a conformation to be produced from a small amount of material .and of easy construction, by which I produce al reliable hub at a small cost and capable -of renewal in all its parts.

In Fig. 3 the thimble portion is produced with annular enlargements E, to receive the inner portion. of the annular ring-hub` ends to give them position on the thimble ends. In this construction of my improved hub, the thimble ends are preferablyproduced in truncated conic form; but instead thereof the ends of the thimble may be produced in cylindrical form, and the hub ends produced to receive them.

A three-part hub consisting of thimble to receive the axlearm, and having itsends produced in truncated-cone form, and annular ring-hub ends of substantially U shape in cross-section, the innerside of each hub end being tapered to fit. upon the thimble, while the outer side of each end is perforated, substan'- tially as described.
